VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 247,911, dated October 4, 1881.

' Application filed August 12,1881. (ModeL) To all whom it may concern:

, Be it known that I, ANDREW HEIN, of Trenton, in the county of Grundy and Stateof Missouri, have invented a new and Improved Vehicle-Wheel, of which the following is afull, clear, and exact description.

The object of this invention is to facilitate the construction and easy running of vehicle wheels. e

The invention consists in providing the hub of the wheel with metallic bands having end cups adaptedto contain boxes that carry rollers that bear on the inner circumference (f the said cups or hub-hand extensions.

In the accompanying drawings, Figure l is a longitudinal sectional elevation of my improved huh on line a at, Fig. 2. Fig. 2 is an end elevation of the same with cup removed. Fig. 3 is a cross-section on line y y, Fig. 1.

Similar letters of reference indicate corresponding part In the drawings, A represents the hub-center, with spokes B radiating from it.

C 0 represent the hub-bands, fittedupon the hub A and conforming to the curves thereof, and held thereon by bolts (1. a, that are passed through their edges or flanges and'through said hub-center A between the spokes B B. These bands'G U are provided with internal annular shoulders, D D, extending at right angles to the faces of the bands (J G, and fitting closely against the ends of the bub-center A, the openings in'said shoulders being of sufiicient diameter to permit the free movement of the axle E. The ends of these hub-bands U are extended into cylindrical cups or sockets F Ffor containing the boxes G G. These boxes G G are' preferably made of cast metal, and have formed in their under surfaces, as shown at I) 1), parallel and connecting grooves for the accommodation of the rolls H H. The front end of the axle E is of square cross-section, and the front box, G, is driven thereon, and held in place by screw 0, that is screwed into the axle end, as shown in Fig. 1. The axle E within the rear or inner cup or socket, F,

is round, and theinner box,G, is held thereon by a key or spline, d, as shown in Figs. 1 and 3. These boxes G G have flanges fffornied at each end of the grooves 12 b, to afford supports for the screw-bolts I I, that are passed through them and the anti-friction rolls H H, and serve as axles for the latter to rcvol ve upon.

The boxes G G themselves being of somewhat less diameter than the cups or sockets F F, and the central bore of the hub A being of greater diameter than the axle E, the whole weight of the said axle E and the load supported by it must reston the rolls H H, which run on th inner faces of the cups F F, so that the vehicle-wheel will run more easily.

The open ends of the cups or band-sockets F F are closedl'or keeping out dust and dirt by screw-caps K, fitted thereon, and held in place by screws It passed through their flanges into the said sockets F F, and on removing these screws oil for lubricating the parts may be introduced through the screw holes.

Havingth'us describedniy invention, I claim as new and desire to secure by Letters Paten t l. Avehicle-wheel constructed,substantially as herein shown and described, with hub-center A, bands 0 J. provided with internal annular shoulders, D D, cups F F, and boxes G G, carrying anti-friction rolls H H, arranged as set forth.

2. In a vehicle-wheel, the combination, with' the bands 0, provided with the cups or sockets F F.of the boxes G G, providedwith the fiangesf, and the rollers Ii, journaled between said flanges by the bolts l, substantially as and for. the purpose set forth.

3. In a vehicle-wheel, the combination, with the hub-center A, of the binds C, secured to'
